Iksar Bone Chip Quest

[Zziek]

Is the bone chip turn in quest for cabilis still bugged as I've seen mentioned on the wiki, where if one faction is maxed out you can no longer raise the other factions? I'm attempting to build Cabilis faction as a Wood Elf and I've maxed out my faction with the Legion of Cabilis, but the Crusaders of Greenmist are still scowling at me. When I hand in bone chips to Trooper Mozo, he mentions that he doesn't see four bone chips, but I'm still awarded the exp and faction messages.

I'm concerned that I won't be able to carry my faction any further, so I want to see if anybody is able to fill me in on whether or not I can move forward with bone chips or if I need to do something else.
